How to restore iPod
(ARTICLE NUMBER HT1339)
Open iTunes, and then connect your iPod to your computer using the USB or FireWire cable that came with your iPod.

After a few moments, your iPod will appear in the Source panel in iTunes.
Select your iPod in the Source panel and you will see information about your iPod appear in the Summary tab of the main iTunes windows.

Click the Restore button. You will be prompted with one or more restore options that may prompt iTunes to automatically download the latest iPod Software.

If you are using a Mac, a message will appear prompting you to enter an administrator’s name and password.

A progress bar will appear on the computer screen indicating that the first stage of the restore process has started.

When this stage is completed,
iTunes will present one of two messages on screen with instructions specific to the iPod model you are restoring.
Restore Instruction 1: Disconnect iPod and connect it to iPod Power Adapter (typically applies to older iPod models).

During the stage 2 of the restore process, the iPod will show an Apple logo as well as a progress bar at the bottom of the display.
It is critical that the iPod remains connected to the computer or iPod Power adapter during this stage.

Note: The progress bar may be difficult to see since the backlight on the iPod display may be off.

After stage 2 of the restore process is complete and the iPod is connected to the computer, the iTunes Setup Assistant window will appear asking you to
name your iPod and choose your syncing preferences similar to when you connected your iPod for the first time.

Very, very silly move. Apple builds Mac's so why would they use windows formatting?? Search for and download a trial version of the program macdrive. This will allow you to look at drives as though they were on a mac and also format them. Plug in your iPod. Find the right drive letter for your iPod, right click on it, and select 'Format Mac Disk...' Then itunes should see your iPod and you can restore it.
